IMPROVEMENT, IN COFFEE-'ROASTERS.

Specification forming part of'Letters Patent No. 35,758, dated July 1, 1802.

To all whom it may concern.-

Be it known that I, EDWARD J. HYDE, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Coffee-Roaster and Stove Combined; and I do hereby declare thatthe followingis a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical transverse section of my improved combined coffee roaster and stove. Fig. 2 is an end view of the same, the parts being adjusted for discharging the roasted coffee. Fig. 3 is a perspective view, the parts being in nearly the same positions as in Fig. 2. Fig. 4 is a section of the stove with the roasting-cylinder removed from it entirely.

Similar letters of reference in the several figures indicate corresponding parts.

The nature of my invention consists, first, in an organization which comprises a stove constructed with a fire'grate and a divided nearlycylindric drum, a regulating-damper, a swinging crane, and a revolving cylinder with a crank-shaft; second, in a manner of arranging the crane and coffee-cylinder so that the cylinder revolves on the crane while the roasting process is being performed, and that the crane swings with the cylinder out of the stove to discharge the roasted coffee and receive a fresh supply; third, in a construction of the fixed part of the drum of the stove with one of its end pieces narrow and the other wide, and the adjustable section of the drum with one of its end pieces wide and the other narrow, but in a converse order to that of the may be passed directly off to .the flue, or

nearly around the coffee-cylinder before it reaches the line, during the process of roasting; fifth, in having the coffee-roaster and heater so combined that the roaster may be removed and the heater used simply for warm ing the room.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A represents the stove constructed with ashdrawer B, grate O, draft-flue D, and an adjustable piece, E, which serves as a fuel-door, and may be thrown up so as to convert the stove into an open Franklin. or thrown down so as to make it a close stove. The door E might be fitted to slide or to open by means of turn-buttons, or in any other wellknown way, and yet not depart from the spirit of my invention.

At one end of the stationary portion of the stove, about one-half the width of the end piece is cut away, as indicated at a, Fig. 2. At the other .end about that amount of width as was removed at a is added to the end piece of the stove, as indicated at b, Fig. 3.

The hinged pieceE is attached to the upper edge of the stationary drum portion of the stove, and its end pieces are constructedone narrow and the other wide, as indicated at 0 d-so as to fit over the respective end pieces a b'to the extent necessary to make a close stove while roasting coffee, the end pieces 0 (1 closing the space a and the slot 6, which are formed for a purpose presently stated.

\Vithin this stove an angular crane, E, is arranged so that it has its axis at one end of the-stove, its supportsfg being formed on or attached to the inside of the stove, as shown in the drawings. The vertical limbs of the crane have journal-brackets h h formed on or attached to them at such points as will suit for a proper-sized roasting-cylinderto be revolved below the horizontal limb of the crane, as illus trated in Fig. 2. ln location the crane stands about centrally in the stove, and on its brackets h h, which'are open at top, a cylindri'c coffee-roaster, F, is hung bymeans of a crankshaft, G', which extends through the cylinder, so as to form bearings and a handle, z. This cylinder is provided with a slide, 3', which covers an opening through which the coffee to be roasted is introduced and the roasted coffee discharged.

\Vheu the cylinder is swung on the crane into the stove, the slot 6 admits the crankhandle a to follow, and the circular terminus of the slot affords a support to the shaft.

When the cylinder is swung out of the stove,

either for the purpose of being charged with coffee or uncharged, the space a allows its confined end to stand in the position shown in Fig. 2, or the cylinder to stand at a right an gle to the front of the stove.

In order to swing the cylinder into or out of the stove, the adj-ustable section E of drum part of the stove, must be thrown up to the position shown in Figs. 2 and 3 from the posi tion shown in Fig. 1, or be taken off, in case it is fastened by buttons or fitted to slide.

In Fig. l the manner in which the widened end piece of the hinged portion E closes the space a and overlaps the stationary end piece of drum is shown by dotted lines.

Between the back of the stove-and the cylin der F a damper, H, is pivoted centrally, and

by turning this damper to the position shown in red the'flame from the fire is compelled to pass over the top of the cylinder; but by allowing it to stand as shown in black the flame passes directly to the flue. Thus the quantity of heat may be controlled, as circumstances may require, in the process of roasting coffee.

In case no coffee is required to be roasted for a length of time, the cylinder is lifted out of the crane and set aside and the stove used for simply warming the store or room in which it may be situated, under which use the hinged portion E may be thrown up so as to expose Other substances than coffee may of course be roasted or cooked with the before-described roasting apparatus.

What I claim as my invention, and desire to secure by Letters Patent, is

1. So combining a stove, a crane, and a roaster that the roaster may be revolved upon the crane over the fire, swung out horizontally from the stove to an angular position therewith, and in this position be turned upon the crane to empty its contents, as set forth.

2. The combination, substantially as herein combination with a removable roaster, F, for

the purpose set forth.

Vitness my hand and seal, in the matter of my application for a patent for a combined stove and coffee-roaster, this 7th day of May, A. D. 1862.
